What will a Trump Presidency mean for environmental law? I’m not sure my crystal ball is better than anyone else’s, but here are a few quick thoughts:

It’s still going to be difficult to amend the key statutes, unless the GOP goes nuclear with the filibuster rules. I don’t see Clean Air Act amendments happening. Significant amendments might be possible to the Endangered Species Act and Superfund.

Changing regulations is more difficult than one might think. As has already been noted, the Bush administration did not fare too well with judicial review of its efforts to roll back some Clinton environmental initiatives. For example, I still think that the new ozone standard should survive and I think that courts would take a dim view of EPA efforts to raise it. The Clean Power Plan is another matter. All Trump needs there may be a new Supreme Court Justice.

The easiest target is executive orders. The social cost of carbon? Toast. Guidance on incorporating climate change into NEPA? Toast.

Trying to keep things light, I’ll close with a summary in haiku, which often takes nature as its subject.
